pALERT F330 Force Balance Accelerometer
pALERT F330 features a high-precision triaxial force-balanced accelerometer to enhance its performance which offers three trigger logics (Pd, PGA, STA/LTA) and filtering options, including high-pass and low-pass filters to reduce non-natural seismic noise. Notably, it incorporates Pd seismic early warning technology, which issues alerts before the arrival of shear waves, reducing earthquake-related disasters. It can estimate S-wave destructiveness when the P-wave displacement exceeds a threshold within 3 seconds.

Description
Introduction
pALERT F330 features a high-precision triaxial force-balanced accelerometer to enhance its performance which offers three trigger logics (Pd, PGA, STA/LTA) and filtering options, including high-pass and low-pass filters to reduce non-natural seismic noise. Notably, it incorporates Pd seismic early warning technology, which issues alerts before the arrival of shear waves, reducing earthquake-related disasters. It can estimate S-wave destructiveness when the P-wave displacement exceeds a threshold within 3 seconds.
pALERT F330 stores historical seismic data, including trigger time, maximum seismic intensity, PGA values for the three axes, and synthetic vector acceleration. It can synchronize with GPS or NTP network time for precise timekeeping. With strong networking capabilities, it can instantly upload earthquake warning information to three servers, and waveform records can be accessed via a browser for analysis. The device supports various seismic intensity scales, such as the 2020 New Seismic Intensity Scale of the Central Weather Bureau, China’s Strong Earthquake Intensity Scale (GB/T-17742-2008), and the international MMI scale, providing flexibility to users based on their specific needs.
